The lights at Lumen Field were blinding, the rain was that classic Pacific Northwest mist, and honestly, the vibe felt off for San Francisco from the jump. If you're looking for the quick answer to who won the San Francisco Forty Niners game today, it was the Seattle Seahawks. And it wasn't particularly close.
Seattle walked away with a dominant 41-6 victory on Saturday night, January 17, 2026. Because the game wrapped up late last night, the fallout is what everyone is talking about this morning. It was a divisional-round blowout that absolutely nobody—especially not the Faithful—saw coming.
The Play That Broke the Game
Sometimes a game is decided in the fourth quarter. Sometimes it’s decided before the fans even sit down with their beers. This was the latter. Rashid Shaheed, the Seahawks' explosive returner, took the opening kickoff 95 yards to the house.
Lumen Field exploded.
Basically, the 49ers spent the next three hours chasing a ghost.
San Francisco has always been known for their poise under Kyle Shanahan, but they looked rattled. Brock Purdy faced a relentless Seattle pass rush that seemed to know exactly when he was going to hitch. It didn't help that the injury bug, which has been biting the Niners all season, decided to take a massive chunk out of them on the biggest stage.

Why the Score Was So Lopsided
You’ve got to look at the turnovers. That’s where the real story lives. The Seahawks' defense, which finished the 2025-2026 regular season ranked number one in scoring defense, played like a group possessed.
They forced three takeaways.
Ernest Jones IV was everywhere. He snagged an interception and forced a fumble that essentially killed any momentum San Francisco tried to build in the second half. When you give a Sam Darnold-led offense short fields over and over again, you’re going to get burned.
Darnold didn't have to be a hero. He just had to be efficient. He leaned heavily on Kenneth Walker III, who was a total monster on the ground. Walker finished with 145 yards and three touchdowns. It felt like every time he touched the ball, he was falling forward for six yards.
The Injury Factor
We have to talk about Christian McCaffrey. He’s the engine of that offense. Late in the game, he went off with a shoulder injury. While he eventually returned to the field, he never looked like himself. He averaged a meager 2.7 yards per carry.

When CMC isn't "CMC-ing," the Niners' offense gets predictable.
- Nick Bosa was already out.
- George Kittle was a scratch before the game.
- Fred Warner’s absence in the middle of the defense was glaring.
Without those pillars, the 49ers looked like a shell of the team that fought through the Wild Card round against Philadelphia. It was a "perfect storm" of bad luck and elite execution from the home team.
The Statistical Reality
If you just look at the box score, it looks like a typo. San Francisco managed only two field goals. Both of those came in the second quarter when it looked like they might actually make a game of it, trailing 17-6. But a scoreless second half is a death sentence in the NFL playoffs.
Seattle's Mike Macdonald has seemingly figured out the Shanahan code. This was the third time these rivals met this season, and the second time in three weeks that Seattle's defense held Purdy to his lowest career outputs.
What Happens Next for the 49ers?
This loss marks the worst playoff defeat for San Francisco in nearly forty years. It’s a bitter pill to swallow for a team that has been a perennial Super Bowl favorite.

The focus now shifts to the offseason. The roster is aging in key spots, and the cap situation is getting tight. Most fans are asking if the "window" is starting to creak shut, or if this was just a fluke season defined by the training room rather than the locker room.
For Seattle, they move on to the NFC Championship game. They’ll be hosting the winner of the Rams vs. Bears game.
If you are a Niners fan, the next step is simple but painful:
- Monitor the injury reports for McCaffrey and Purdy over the coming week to see the true extent of the damage.
- Watch the coaching carousel; several 49ers assistants are expected to be targeted for head coaching vacancies.
- Turn your eyes toward the 2026 NFL Draft, where San Francisco will likely need to prioritize offensive line depth and secondary help to keep pace with a rejuvenated Seattle squad.
The 2025-2026 season for San Francisco is officially in the books. It didn't end with a parade, but with a quiet flight back to the Bay.
